Inlet Pressure Calibration (LTV
®
1200 Only)
To perform the O
2
inlet pressure calibration, you will need the following equipment:
• Gas source capable of 80 PSI with a T-connection to a pressure gauge and an O
2
inlet connector.
O
2
leak test
1) Remove the O
2
inlet port cap and connect the high pressure gas source to the O
2
inlet
port. Set the O
2
supply to approximately 50 PSI.
2) Turn off the O
2
supply.
3) Observe the gauge and record any drop in pressure
Requirements: The leakage rate shall be ≤ 1 PSI in one (1) minute.
4) Record the leakage value on the Calibration Worksheet.
To calibrate the O
2
inlet pressure transducer
1) Press the Select button while O2 INLET is displayed.
O2 50 PSI is displayed.
2) Increase to and maintain the pressure at 50.0 ±0.2 PSI.
